Jennifer Aniston recently gushed that her happiness level is at "10-plus," a fact that apparently isn't sitting well with one tabloid. Grazia magazine (via the London Daily Mail) seems to be doing its darndest to turn the actress' smile upside-down by claiming she's on the outs (yet again) with longtime BFF and former "Friends" co-star Courteney Cox.

The blame for the alleged downgrade in their bosom-buddy status is placed squarely on Aniston's insta-serious relationship with Justin Theroux.

The evidence, such as it is, includes Courteney's absence at Jen's recent Hollywood Walk of Fame ceremony. Oh, and Aniston, who is godmother to Cox's 7-year-old daughter, Coco, supposedly bailed out of a planned girls night last month in order to cuddle up with live-in honey Theroux.

All this, contends the mag, has left the "Cougar Town" star upset, apparently because she was there for Aniston after her breakup with Brad Pitt and feels she deserves the same kind of support now that she's the single one, having split from David Arquette in October 2010 after 11 years of marriage.

But before you shed a tear at the thought of Monica and Rachel no longer exchanging girl talk at Central Perk, keep a couple things in mind: Courteney dismissed the fractured friendship rumors to Howard Stern last month ("We're very close. I'm having dinner with her tonight," she said), and she quietly attended the Los Angeles premiere of Jen and Justin's flick "Wanderlust" on Feb. 16.

Need more proof?

Aniston's rep also scoffs at the story, telling Wonderwall that it's "completely untrue" and "resurrects itself every six months."
